🔍 Key Concepts

• International & Inland Navigation Rules – Lights for vessels being towed • Difference between towing vessel’s lights and tow (the vessel or object being towed) • How a vessel shows its status when it has no power of its own at night

💭 Think About

• Think about what lights the towing vessel shows, and then separately what the object being towed must show. Which set applies to the disabled vessel itself? • If a vessel is broken down and under tow, is it still considered ‘underway by its own power’ or more like an ‘object in tow’ such as a barge or similar unit? • Which of the listed choices best matches the simple, standard lighting arrangement required for a vessel or unit that is being towed and is not itself doing the towing?

✅ Before You Answer

• Verify in the Navigation Rules what lights are required for the tow itself (the vessel/objects being towed), not for the tug. • Check which of the answer choices represents a simple towed unit instead of a self‑propelled or anchoring status. • Confirm that a broken down vessel under tow does not display the same lights as the towing vessel that is providing the propulsion.
